I bought regular Duracell Alkaline battery at Costco. It is AA size. I used it on the clock, radio, remote controller etc. And at the same time, I would like to use the rechargeable battery for other devices. Such as Xbox wireless controller. My son and I play the game very often. The shacking function makes the battery run faster.

There are two type of packs. One is 4 batteries, $12.99. The other one is 8 batteries, $26.99.

It doesn’t make sense. I can buy two boxes of 4-pack. The total is $12.99×2 = $25.98. It is cheaper thant the 8-pack.

The product description.

Imagine leaving a battery in a toy car. The battery slowly drains until it’s completely empty. This damages many rechargeable batteries and causes a shorter runtime. The AmazonBasics Batteries stay strong and keep their capacity.

You want your flashlight to be ready when you need it. Flashlights using ordinary batteries can dim after sitting unused for too long. AmazonBasics Batteries shine bright even after storage. They are perfect for high-power, high-drain devices.

With a low self-discharge technology, your batteries can sit for years and still be ready when you need power. For the best performance, store fully charged batteries at about 68°F/20°C.

Don’t be limited by batteries. AmazonBasics Batteries work well with a variety of electronics, including high-power devices such as digital cameras, electric toothbrushes, and flashlights.

When you need batteries that perform well even in -4°F, these batteries maintain high power in low temps. They’re great for ski resorts and winter activities.

In my own words. The AmazonBasic batteryies has a better capacity, even after years storage. More usages than regular one and Alkaline battery.
